Ruby on rails 如何解决这个路由错误？

因此，出于某种原因，我在尝试发布到该url时没有收到任何路由匹配/记帐/付款对象/57/注释

正如您可以从rake路由中看到的，该url是路由的

现在有点奇怪，GET请求有效，但POST请求无效

我还可以使用_pathhelper方法生成路由

accounting_payment_object_comments GET    /accounting/payment_objects/:payment_object_id/comments(.:format)                             {:action=>"index", :controller=>"accounting/comments"}
                                   POST   /accounting/payment_objects/:payment_object_id/comments(.:format)                             {:action=>"create", :controller=>"accounting/comments"}

但当我发布到它时，log会返回以下内容：

Started POST "/accounting/payment_objects/57/comments" for 127.0.0.1 at Fri Jul 22 14:53:58 +0800 2011

ActionController::RoutingError (No route matches "/accounting/payment_objects/57/comments"):


Rendered /Users/pma/.rvm/gems/ree-1.8.7-2010.02/gems/actionpack-3.0.9/lib/action_dispatch/middleware/templates/rescues/routing_error.erb within rescues/layout (0.7ms)

我已确认这与我的控制器/操作无关

但我的routes.rb中有一段代码与此问题相关

  namespace 'accounting' do
    resource :requisitions, :only => [:show] do
      collection do
        get 'filter'
      end
    end
    resource :purchase_orders, :only => [:show]
    resource :accounts_payable, :only => [:show]
    resource :payment_requests, :only => [:show, :update]
    resource :general_ledger, :only => [:show]
    resource :permissions, :only => [:update]

    resources :payment_objects do
      collection do
        get 'filter'
        post 'permissions'
      end
      member do
        match 'approve'
        match 'decline'
      end
      resources :items do
        member do
          get 'receive' => 'items#received_form'
          post 'receive' => 'items#process_received_form'
        end
        resources :receiving_records, :only => [:create, :new]
      end
      resources :files
      resources :comments, :except => [:show, :new]
    end
  end

这是因为表单中有两个按钮

其中一个方法必须设置为其他方法

可能导致此问题的表单示例：

<%= form_for @comment, :url => @create_url, :method => :post do |f| %>
  <%= f.text_area :content %>
  <div class="space inline">
    <%= f.submit %>
    <%= button_to 'Discard Draft', @discard_url, :id => 'discard_draft_link', :method => :delete %>
    <p id="draft_save_message">
      <% if @draft %>
        Draft was last saved at: <%= @draft.updated_at.getlocal %>
      <% else %>
        Draft not saved yet.
      <% end %>
    </p>
  </div>
<% end %>

如果您将按钮更改为链接或将其移出表单块，这将解决您遇到的任何问题。

我在记帐命名空间中实际上没有注释控制器，但我可以使用相同的资源路由检索索引。您是否可以发布带有索引操作请求的日志？
